#19539 new defect
CPU overcranks on Macbook Air i5 early 2020 after sleep (either guest OS or host)

Description
Debian and Ubuntu guests operate normally until after waking from sleep -- either suspending the guest while leaving the OS awake, or sleeping the host OS with the guest either awake or asleep. After waking from any of those states, the CPU maxes out to the thermal limit and stays there until the guest is halted, after which CPU behavior reverts to normal and temperatures stabilize at normal levels (40-55 C depending on other operations). This happens even when all other applications are off. Since it includes both guest and host, this may be two separate problems. Occasionally it does not happen with guest suspend, but it is 100% with the host os sleep. This does not happen on my 2018 Mac Mini, so as far as I know it's specific to the new Macbook Air.
Happens every time with guest suspend since I submitted. I suspect my initial data was bad (as in wetware memory).
Okay, here's a preliminary: if I turn off guest sound via virtualbox prefs the problem disappears. I'll inspect further and see if some option allows me to activate sound (though I was unable to get it to work at all).
Shamefully, I didn't identify the guest: Debian Buster 10.3 with OpenBox in Virtualbox 6.0.20; I was unable to get a 6.1.6 gues to work properly but may try again w/o sound.
